WILLIAM C. TOELLNER, OF BUNCETON, MISSOURI.

. ATTACHMENT FOR nnnmrons.

Application filed June 18, 1921.

trolled from the drivers seat, for regulating the amount of air passing through the radiator or for entirely shutting off the flow of air through-the radiator.

Another object of the invention is to provide means whereby the air opening in'the device is so controlled that the lower partthereof will'be last to open and the first toclose, thus preventing the water in the radiator from freezing at the bottom thereof, Where the water is the coolest. I

This invention also consists in certain other fe tures of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, il-" lustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a slde view of a portion of an automobile showing my invention in use.

Figure 2 is a front view.

Figure 3 is an enlarged vertical sectional view through the invention.

Figure 4 is a section on line 44 of Figure 3.

Figures 5 and 6 are detail views.

In these views 1 indicates the cover member which is adapted to be secured to the front part of the radiator A by means of the bolts 2 which pass between the water tubes of the radiatorand are provided with suitable washers and nuts for securing the parts in position. As shown the cover member is provided with an opening 4 through whichair can pass to come in contact with the water tubes of the radiator. The lower part of the cover member extends a considerable distance below the bottom of the red;-

ator, as shown at 5, so that the said lower Serial No. 478,698.

" part of the radiator is well protected by the device. A pair of guiding grooves 6 are formed in each side wall of opening 4, one groove being of greater length than the other and said grooves receive the ends of the shutters 7 and 7. The lower shutter 7' works in the short grooves and the upper shutter 7- works in the long grooves. Strips 8 of leather or the like may be fastened to the ends of the shutters to prevent them from rattling in the grooves. The upper shutter has its lower edge bent into hook shape, as shown at 9, and the lower shutter has its upper edge bent inwardly and downwardly into hook shape,.as shown at 10, and these'two bent edges are adapted to engage with each other so that the upper'shutter will pull upwardly the lower shutter as said upper shutter isinoved upwardly to close the opening. The lower edge of the lower shutter is rolled around a wire, as shown at 11, and the lower edge of opening 4 is also rolled around a wire, as shown at 12, and these parts coming in contact with each other when the shutters are fully closed will thus prevent upward movement of the shutters. The upper edge of the opening 4 may also be rolled around a wire as shown at 13. The upper edge of the upper shutter 7 is bent outwardly at right angles, as

(ill

at 14, and this part will engage the lower edge of the opening 4 when the shutters are in fully open position, thus closing the space between member 1 and the radiator and it will also engage the upper edge of opening 4 when the shutters are fully closed.

A cable15 is connected with the upper edge of the upper shutter 7 and passes over a small pulley 16 carried by the member 1 and passes through a hole in the dash where. it is connected with a chain 17 which is adapted to engage with a holder 18 so that the shutters can be held entirely closed or in open or partly open condition; This holder is provided with a hook 19 and with an opening 20 having a reduced lower per tion for receiving the links of the chain so that a chain can be slacked to any desired extent to permit the shutters to be placed at any desired position.

From the above it will be seenthat the amount of air passing through the radiator can be readily adjusted from the drivers seat and that the said air'can be entirely shut off when desired. It will also be seen that the upper part of the opening is opened first and closed last so that there is nodanger of the water in the lower part of the radiator freezing as this part of the radiator is the last to be uncovered and the first to be covered.

It is thought from the foregoing decription that the advantages and novel features of my invention will be readil apparent.

I desire it to be understoo that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall'within the scope of the appended claim.

What I claim is p A radiator cover comprising a member adapted to be secured to the front face of .the radiator, said member having an opening therein, a projection at the lower edge of the opening and guideways at the sides thereof, the guideways being arranged in upper and lower pairs, the lower pair being of greater width than the upper pair, a

pair of shutters engaging the guide-ways,

both shutters engaging the lower guideways when in open or 1n partly open positionwith the upper shutter engaging the upper guideways when the shutters are in closed position, a projection at the lower edge of the lower shutter for engaging the projection at the lower edge of the opening for limiting the upward movement of the lower shutter, hooks formed on the upper edge of the lower shutter and on the lower edge of the upper shutter for causing movement of the upper shutter to be transmitted to the lower shutter when the hooks engage each other, an outwardly extending .part at the upper edge of the upper shutter for engaging the upper wall of the opening when the shutter is in raised position and means connected with the upper shutter for moving the same.

In testimony whereof I aflix my signature.

WILLIAM C. TOELLNER.
